This patch changes the top-level directory layout as a preparatory
step for improving the tools for managing 3rd-party source codes.

# Support for using standard C++ headers for Genode programs
#
#
# Add the location of the compiler's C++ headers to search path
#
# We add all header locations that have "c++" or "include-fixed" to the search
# path. The 'c++' subdirectory contains the actual standard C++ headers.
# However, for using them together with Boost, we need to access 'limits.h' as
# provided within the 'include-fixed' location.
